Why we were created.

"Why did God create man? To show God! He created little images so that they would talk and act and feel in a way that reveals the way God is. So people would look at the way you behave, look at the way you think, the way you feel, and say, God must be great, God must be real. That is why you exist. God didn't create you as an end in yourself. He's the end, you're the means. And the reason that's such good news is because the best way to show that God is infinitely valuable is to be supremely happy in Him. If God's people are bored with God, they are really bad images. God is not unhappy about Himself. He is infinitely excited about His own glory.

That's why the Son received the words: You are my beloved son. With you I am well pleased. Take those words, "Well pleased." God doesn't say He's okay with Jesus. He's not just okay with Jesus! He is absolutely thrilled with Jesus as the image of Himself  So if we go about the world making our choices in what we watch on television, do on the computer, handle money, use food, so that it communicates to the world that these things are our treasure, rather than God, that these things make us satisfied rather than God, He's getting the bad press, and we're not doing what we were created to do. We were created to image God. So, God predestined for His glory and He created for the display of His glory."
